100 W LED power supplies

21 March 2012 Power Electronics / Power Management

A new series of high-efficiency power supplies for LED lighting, the LDS100 series, was recently announced by Emerson Network Power. The company’s LED lighting products now cover three distinct power output bands – 25, 70 and 100 W – making it easy for original equipment manufacturers and system installers to choose the best power supply for their application.

The new 100 Watt LED power supplies offer a choice of models – featuring an input range of 120 to 277 V a.c. (H models), and an input range of 100 to 240 V a.c. (U model). The first models in the series feature Class 2 outputs capable of delivering up to 4,1 A at 24 V d.c., and offer both constant current and constant voltage output modes, enabling customers to meet the demands of different LED lighting systems with a single model.

Constant voltage mode operates from no load to full load. The LDS100-24-H03 model features programmable current limit levels, controlled via an IEC 60929 compliant interface using a standard 0 to 10 V signal, to support dimming. The current limit level is also resistor programmable and can be preset by the system designer.

The units feature active power factor correction rated at 0,9 minimum to support Energy Star requirements and meet the Class C harmonic requirements of IEC 61000-3-2. The supplies also have a very high conversion efficiency – typically 90% when operating from a nominal 230 V a.c. input. They are rated for operation over a wide case temperature range of -40°C to +90°C, without forced air cooling.

Available with ingress protection ratings as high as IP67, which provides protection against shallow water immersion, LDS100 power supplies are intended for outdoor and ruggedised indoor applications. Housed in a slimline package measuring just 215 x 42 mm, with a height of only 30 mm, the power supplies are easy to accommodate in modern LED lighting fixtures with limited space.

The power supplies comply with the CISPR 15 requirement for EMI and meet FCC part 15 conducted noise standards. They are protected against short circuit, over-voltage and over-temperature conditions. The surge immunity performance of the LDS100 series has been evaluated to installation class 3 (U models) and class 4 (H models) test levels set out in IEC 61000-4-5.

Critical safety specifications include EN 61347-2-13 and UL 8750, which are specific to LED related applications, and the LDS100 series also complies with CSA C22.2 No. 107.1 and CE LVD directives. The flexible nature of the LDS100 design platform also facilitates rapid modification for customer-specific applications.
